SPECIFICATION forming part of Letters Patent N 0. 728,549, dated May 19,1903. Application filed August 28, 1902. Serial No. 121,314. (liemodel.)

To all whom it may concern:

Be it known that I, CHARLES CREToRs, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvementsin'Roasting-Apparatus for Peanuts and the Like, of which the followingis a specification.

The present invention relates to that class of roasting apparatus inwhich the material to be roasted is contained within ahorizontally-rotating cylinder surrounded by an inclosing casing orhousing, within which is also containedaburnerorfirechamber,from whichthe heat required in the roasting operation is supplied; and the presentimprovement has for its object to provide a simple, durable, ande'fiioient construction andarrangement of parts whereby the roastingoperation is performed in a rapid, certain, and-uniform manner and whichin addition involves a stable and efficient support for the revolvingroasting-cylinder,a simple and efficient means for stirring the materialduring the roasting operation, and a convenient means for observing theprogress of the'roasting operation and for testing the material duringsuch progress of the operation, all as will hereinafter more fullyappear, and be more particularly, pointed out in the claims.

In the accompanying drawings, illustrative of the present invention,Figure 1 is a hori-- zontal section at line a; to, Fig. 2, ofa roastingapparatus embodying the present invention 5 Fig. 2, a transverse sectionat line 00 az, Fig.

1; Fig. 3, a transverse section of the roastingcylinder at line 00 00Fig. 1; Fig. 4, an end elevation of the apparatus; Fig. 5, a transversesectional elevation at line .70 Fig. 1.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the main inclosing casing of acylindrical or other suitably-shaped form and having end heads 2 2, towhich such casing 1 is secured, by attaching-flanges on said heads, asshown.

3 is a burner or other like source of heat arranged in the lower part ofthe inclosing casing 1.

4 is a segmental-shaped door closing a longitudinal opening in the upperportion of the casing 1 and affording convenient access to theroasting-cylinder. In the construction shown in the drawings the end ofsuch door is adapted to slide in curved grooves or ways in therespective casing-heads 2, as shown in Figs. .1, 2, and 5.

5 is an imperforate cylinder forming in connection with the end heads 6and 7 the revolving cylinder of the apparatus.

8 is a door in the side of the roasting-cylinder of any usual form andaffording access to the interior of such cylinder.

The heads 6'and 7 areof substantially the same. construction, and eachhead will comprise an annular sash-ring of metal formed with aninwardly-extending annular glazingfillet, as'shown in Fig. 1, and acentral transparent disk9, secured in the socket formed by the filletaforesaid and adapted to afiord a convenient observation of the materialundergoing the process of roasting Without the necessity of stopping theoperation of the apparatus or removing or manipulating any of the parts.v

10 represents ann ular series of perforations in the webs of therespective rings or annulus forthe escape of the vapors generated in theroasting operation and which in the present construction prevents in avery perfect mannerany condensation of such vapors upon the transparentdisks 9, that form the greater portion of the heads 6 and 7.

11 represents circular track-flanges on the headstiand 7, adapted tohaving bearin g upon the series of track rollers, hereinafter described.Such track-flanges are adapted to fit loosely within orifices for thesame in the end heads 2 of the main casing 1, so as to preventaccidental disengagement of the trackfianges aforesaid from theirbearing upon the track-rollers.

12 is a beveled-gear formation near the outer rim of one of the endheads of the roasting-cylinder adapted to mesh with and be driven by abevel-pinion 13 on a counter-shaft 14, which in turn has operativeconnection with a suitable powersource.

15 is a flanged tubular bushing fitting an axial orifice in thetransparent disk 9 of the end heads of the roasting-cylinder andseouredin place by an annular follower-nut 16, screwing upon thescrew-threaded shank of such bushing, as shown in Fig. 1 Such of onebushing is adapted to afford a substantial opening for the introductionof the usual trier, by which a quantity of the material within theroaster-cylinder can be removed for a more intimate and thoroughinspection than can be atforded by a visual inspection through thetransparent end walls 9 of the roaster-cylinder.

17 17 are one or more perforated partitions arranged transverse thelength of the roaster cylinder and dividing the interior of the sameinto a series of separate subchambers, in which the mass of peanuts orother like material are kept in a separated condition, and the bankingup of such material to one end or the other of the roasting-cylinder ispositively prevented. Such banking of the peanuts to one end or theother has been a serious defect in the portable or wagon type ofpeanut-roasting apparatus now in general use.

18 is a fiat stirrer-plate of a less width than the diameter of theroasting-cylinder and arranged centrally within the same and transversethe axis of rotation of such cylinder. Such stirrer-plate extendssubstantially the entire length of the roaster-cylinder and is held inposition by means of stay-bars 19, extending to and secured to the innersurface of the roasting-cylinder, as shown in Figs. 1 and 2. Such plateis preferably formed by a single sheet of metalof the required size, andthe series of partitions 17, heretofore described, are formed withcentral orifices through which the plate passes and is supportedintermediate of its length by the walls of such orifices.

20 and 21 are deflecting plates or vanes 'secured to the opposite sidesof the stirrer-plate 18 and having a reverse angular relation to eachother, as indicated in full and dotted linesin Fig. 1, the arrangementbeing adapted to assist in the stirring operation by im parting analternate longitudinal movement to the material during the rotation ofthe roastercylinder.

In the present improvement the stirrerplate 18 is formed with a centralcut-away portion 22 at the end adjacent to the tubular bushing 15, whichconstitutes the trier-orifice of the roaster cylinder, so as to admit ofthe introduction of the trier in the required axial position and insurethe rapid filling of the same with material by the remaining endportions of the stirrer-plate. 'lhe stay-bar 19, adjacent to said end ofthe stirrerplate, is defiected away from the axis of rotation, as shownin Fig. 2, so as to be out of the path of the trier.

23 23 are pairs of track-rollers journaled in receiving-pockets 24therefor in the end heads 2 of the main casing by means of headedjournal studs 25, which pass through the track-rollers and screw intothe metal at the inner ends of the receiving-pockets aforesaid. Suchtrack-rollers are arranged equidistant at each side of avertical linecutting the axis of rotation of the roaster-cylinder and wholly supportsuch cylinder through the circular track-flanges 11 thereof,which areadapted to have bearing on the periphery of such trackrollers, as shownin Fig. 4.

26 represents a series of knobs secured to the inner faces of thetrack-flanges 11 and adapted to afford convenient means for rotating theroaster-cylinder by hand in the emptying and filling operations and thelike.

27 is the usuallongitudinally-arranged stirrer-blade, secured to theinner wall of the roaster-cylinder to aid in the stirring operation assuch cylinder revolves.
